FIELD OF THE INVENTION

The present invention generally relates to a method of preparing a flavored coffee and a composition used therefor, and more particularly, relates to a method of preparing a flavored coffee using reduced amount of flavorant, and a coffee composition used for preparing such flavored coffee.

BACKGROUND OF THE INVENTION

A flavorant is typically added to a food or drink to impart a desired flavor into the food or drink. However, the larger the amount of flavorant used, the more “unnatural” or “artificial” will be the consumer's perception of the flavor of the food or drink. Moreover, using a larger amount of flavorant is not cost-effective either.

Thus, there exists a need for a method of preparing a flavored food/drink, such as coffee, using a reduced amount of flavorant, but not at the cost of decreasing the consumer's perceived acceptability associated with the flavor.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide method of preparing a coffee beverage using reduced amount of flavorant, but still giving a “full” flavor perception.

It is another object of the present invention to provide a coffee composition comprising a roasted and ground coffee and a reduced amount of flavorant, which, upon brewing, produces a coffee beverage having a “full” flavor perception.

These and other non-limiting aspects of the present disclosure are discussed further herein. The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its advantages and specific objects attained by its uses, reference is made to the accompanying descriptive matter in which various embodiments of the invention are illustrated.

DETAILED DESCRIPTION OF THE INVENTION

The following discussion is presented to enable a person skilled in the art to make and use one or more of the present embodiments. The general principles described herein may be applied to embodiments and applications other than those detailed below without departing from the spirit and scope of the disclosure. Therefore, the present embodiments are not intended to be limited to the particular embodiments shown, but are to be accorded the widest scope consistent with the principles and features disclosed or suggested herein.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for describing particular embodiments only and is not intended to be limiting of the invention. As used in the description of the invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. All publications, patent applications, patents, and other references mentioned herein are incorporated by reference in their entirety as though they were fully set forth herein.

Unless otherwise indicated, all numbers expressing quantities of ingredients, properties such as molecular weight, reaction conditions, and so forth as used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless otherwise indicated, the numerical properties set forth in the following specification and claims are approximations that may vary depending on the desired properties sought to be obtained in embodiments of the present invention. Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, the numerical values set forth in the specific examples are reported with relative precision. Any numerical values, however, inherently contain certain errors necessarily resulting from error found in their respective measurements.

In various embodiments of the invention, an amount of colorant is used to replace a portion of the flavorant present in a flavored coffee beverage or brew. Surprisingly, the flavor perception of the coffee beverage or brew containing less amount of flavorant is equivalent to that of the original coffee beverage or brew containing a standard (i.e., higher) amount of flavorant.

An embodiment of the invention is represented by the first coffee composition as described in the SUMMARY OF THE INVENTION. The first coffee composition comprises a colorant, a flavorant, and a roasted and ground coffee. The amount of the colorant is C>0 parts, and the amount of the flavorant is (F−ΔF)>0 parts wherein (F×20.1%)≥ΔF>0, based on 100 parts by weight of said roasted and ground coffee. The second coffee composition, used as the control in the present invention, is the same as the first coffee composition except that C=0 and ΔF=0. In other words, the second coffee composition comprises C=0 parts of colorant and F parts of flavorant, based on 100 parts by weight of the roasted and ground coffee. In contrast, the first coffee composition contains C parts more colorant, but ΔF parts less flavorant, than the second coffee composition. However, coffee beverages made from the coffee composition or first coffee composition, with the reduced amount of flavorant up to 20.1% and appropriate colorant added thereto, are perceived as having a full amount of flavor, i.e., same strength as coffee beverages made using a standard amount of flavorant, with no colorant added.

An embodiment of the invention is represented by the coffee composition or first coffee composition as described in the SUMMARY OF THE INVENTION. The coffee composition or first coffee composition comprises a colorant, a flavorant, and a roasted and ground coffee. The amount of the colorant is C>0 parts, and the amount of the flavorant is (F−ΔF)>0 parts wherein (F×20.3%)≥ΔF>0, based on 100 parts by weight of said roasted and ground coffee. The control coffee composition, used in the control coffee brew in the present invention, is the same as the coffee composition or first coffee composition except that C=0 and ΔF=0. In other words, the control coffee composition comprises C=0 parts of colorant and F parts of flavorant, based on 100 parts by weight of the roasted and ground coffee. In contrast, the coffee composition or first coffee composition contains C parts more colorant, but ΔF parts less flavorant, than the control coffee composition. However, coffee brew made from the coffee composition or first coffee composition, with the reduced amount of flavorant up to 20.3% and appropriate colorant added thereto, are perceived as having a full amount of flavor, i.e., same strength as coffee brews made using a standard amount of flavorant, with no colorant added.

Roasted and Ground Coffee:

Roasted and ground coffee in the present invention may be made from any coffee beans or mixture thereof, either in their natural state or after being subject to various mechanical, physical, chemical, and/or biological treatments. Coffee beans are the seeds of “cherries” that grow on coffee trees in a narrow subtropical region around the world. There are many coffee varieties, however, it is generally recognized that there are two primary commercial coffee species: Coffea arabica (herein “Arabica(s)”) and Coffea canephora var. robusta (herein “Robusta(s)”). Coffees from the species arabica may be described as “Brazils,” which come from Brazil, or “Other Milds” which are grown in other premium coffee producing countries. Premium Arabica countries are generally recognized as including Colombia, Guatemala, Sumatra, Indonesia, Costa Rica, Mexico, United States (Hawaii), El Salvador, Peru, Kenya, Ethiopia and Jamaica. Coffees from the species canephora var. robusta are typically used as a low cost extender or as a source of additional caffeine for Arabica coffees. These Robusta coffees are typically grown in the lower regions of West and Central Africa, India, South East Asia, Indonesia, and Brazil.

When removed from the coffee cherry, coffee beans normally have a distinctly green color and a high moisture content. Therefore, they are normally dried prior to export, typically to a moisture content of about 12%. Historically, solar drying was the method of choice, although machine drying is now normally used due to the reliability and efficiency of the machine dryers available for this purpose. After drying to a moisture content of about 12%, the coffee beans are typically exported to consuming nations where they are processed into conventional ground roast coffee by roasting followed by grinding. Any of the variety of roasting techniques known to the art can be used to roast the green coffee in the process of this invention. In the normal operation of preparing conventional roast and ground coffee, coffee beans may be roasted in a hot gas medium at temperature ranges of about 176.8-371.1° C. (350-700° F.), with the time of roasting being dependent on the flavor characteristics desired in the coffee beverage or brew when brewed. Where coffee beans are roasted in a batch process, the batch roasting time at the hereinbefore given temperatures is generally from about 2 minutes to about 20 minutes. Where coffee beans are roasted in a continuous process, the residence time of the coffee beans in the roaster is typically from about 30 seconds to about 9 minutes. The roasting procedure can involve static bed roasting as well as fluidized bed roasting. While any method of heat transfer can be used in this regard, convective heat transfer, especially forced convection, is normally used for convenience. The convective media can be an inert gas or, more typically, air. Typically, the beans are charged to a bubbling bed or fluidized bed roaster where they contact a hot air stream at inlet air temperature of from about 350° to about 1200° F. (about 177° C. to about 649° C.), at roast times form about 10 seconds to not longer than about 5.5 minutes.

As well known to coffee professionals, it is conventional to refer to the degree or extent to which coffee beans are roasted in terms of their Hunter color level. The Hunter Color “L” scale system is generally used to define the color of the coffee beans and the degree to which they have been roasted. Hunter Color “L” scale values are units of light reflectance measurement, and the higher the value is, the lighter the color is since a lighter colored material reflects more light. Thus, in measuring degrees of roast, the lower the “L” scale value the greater the degree of roast, since the greater the degree of roast, the darker is the color of the roasted bean. This roast color is usually measured on the roasted, quenched and cooled coffee beans prior to subsequent processing (e.g., grinding and/or flaking) into a brewed coffee product. However, color may be measured on finished product, in which case the color will be designated as such. The ground roast coffee of the invention can be made from coffee beans roasted to any desired roast color from about 10 L (very dark) to about 25 L (very light).

Once the coffee beans are roasted, they are ground to a desired average particle size. Average particles sizes on the order of as low as 250 μm (microns) and as high as 3 mm, as measured by Laser Diffraction on a Sympatec Rodos Helos laser particle size analyzer, are conventional. Coffee flakes can also be used.

What may also be used is a mixture of ground roast coffees having different densities, different Hunter L colors, different particle sizes, different moisture contents, and different combinations thereof (i.e., one ground roast coffee could have a low density and a high moisture content while another ground roast coffee could have a medium density and a low moisture content). Thus, the ground roast coffees can be mixtures of regular and high density coffees, mixtures of regular and low density coffees, mixtures of high and low density coffees, and mixtures of high, regular and low density coffees, if desired.

Flavorants:

The flavorants that can be used include those known to the skilled artisan, such as natural and artificial flavorants. These flavorants may be chosen from synthetic flavor oils and flavoring aromatics, and/or oils, oleo resins and extracts derived from plants, leaves, flowers, fruits and so forth, and combinations thereof. Representative flavor oils include: cinnamon oil, hazelnut oil, cocoa oil, peppermint oil, oil of nutmeg, oil of sage, and oil of bitter almonds. Also useful are artificial, natural or synthetic fruit flavorants such as vanilla, chocolate, coffee, cocoa and citrus oil, including lemon and orange, grapefruit and fruit essences including apple, peach, strawberry, raspberry, and so forth. These flavorants can be used individually or in admixture. Commonly used flavors include mints such as peppermint, artificial vanilla, cinnamon derivatives, and various fruit flavors, whether employed individually or in admixture. Flavorants such as aldehydes and esters including cinnamyl acetate, cinnamaldehyde, citral, diethylacetal, dihydrocarvyl acetate, eugenyl formate, p-methylanisole, and so forth may also be used. Generally, any flavorants or food additive, such as those described in Chemicals Used in Food Processing, publication 1274 by the National Academy of Sciences, pages 63-258, may be used. Further examples of aldehyde flavorings common to flavoring coffee include, but are not limited to acetaldehyde (apple); benzaldehyde (cherry, almond); cinnamic aldehyde (cinnamon); citral, i.e., alpha citral (lemon, lime); neral, i.e. beta citral (lemon, lime); decanal (orange, lemon); ethyl vanillin (vanilla, cream); heliotropine, i.e., piperonal (vanilla, cream); vanillin (vanilla, cream); alpha-amyl cinnamaldehyde (spicy fruity flavors); butyraldehyde (butter); valeraldehyde (butter); citronellal (modifies, many types); decanal (citrus fruits); aldehyde C-8 (citrus fruits); aldehyde C-9 (citrus fruits); aldehyde C-12 (citrus fruits); 2-ethyl butyraldehyde (berry fruits); hexenal, i.e. trans-2 (berry fruits); tolyl aldehyde (cherry, almond); veratraldehyde (vanilla); 2-6-dimethyloctanal (green fruit); and 2-dodecenal (citrus, mandarin); cherry; grape; mixtures thereof; and the like.

Colorants:

The colorants of the invention are used in amounts effective to produce the desired color. The useful colorants include pigments such as titanium dioxide. Colorants can also include natural food colors and dyes suitable for food, drug and cosmetic applications. These colorants are known as FD&C dyes and lakes. The materials acceptable for the foregoing spectrum of use are typically water-soluble, and include FD&C Blue No. 2, which is the disodium salt of 5, 5-indigotindisulfonic acid. Similarly, the dye known as FD&C Green No. 3 comprises a triphenylmethane dye and is the monosodium salt of 4-[4-N-ethyl-p-sulfobenzylamino) diphenyl-methylene]-[1-N-ethyl-N-p-sulfonium benzyl)-2,5-cyclo-hexadienimine]. Examples of colorant include Cherry Liquid Color Solution 00385 (a mixture of FD&C Blue #1 and FD&C Red #40), Yellow Liquid Color Solution 00417 (FD&C Yellow #5), Lime Green Liquid Color Solution 00317 (FD&C Green #3), Emerald Green Color Solution 00308 (a mixture of FD&C Blue #1 and FD&C Yellow #5), Cream Yellow Liquid Color Solution 00307 (a mixture of FD&C Yellow #5 and FD&C Yellow #6), Blueberry Liquid Color Solution 00658 (a mixture of FD&C Red #40 and FD&C Blue #1), Blue Liquid Color Solution 00767 FD&C Blue #1), and Red Liquid Color Solution 00325 (FD&C Red #40), which are all commercially available from Sensient, St. Louis, Mo.

In providing the coffee composition, the flavorant and the colorant (if any) and the roasted and ground coffee may be blended into a homogenous mixture using known techniques. Preferably, the mixture is sealed into an air-tight bag to prevent degradation during storage.

The first coffee composition (as well as the second coffee composition) is subject to an extraction step (i.e. step (ii) in SUMMARY OF THE INVENTION) using water to make a coffee brew, commonly known as black coffee. Typical methods for brewing roast and ground coffee suitable for use with the invention include, for example, but are not limited to automatic drip coffee makers (ADC), single cup coffee making devices utilizing a single serving of coffee contained within a unit such as a cup, disk, pod, or capsule, French press, electric espresso/cappucchino makers, percolators, Moka pot/stove top espresso makers, drip-type/non-electric coffee makers, and coffee strainers.

As known to the skilled artisan, the amount of water used in this step may be in the range of from about 20 to about 30 ml per gram of the coffee composition. For example, 1420 ml of water may be used to extract 58.5 grams of the coffee composition, which indicates a usage of water in the amount of 24.4 ml per gram of the coffee composition. Although there is no specific limitation on the temperature of the water used in this step, in preferred embodiments, the water temperature is from about 185° F. to about 205° F., such as 195° F. The extraction step may be carried out with any suitable device, and in preferred embodiments, an Automatic Drip Coffee (ADC) Maker is used.

In step (iii) of SUMMARY OF THE INVENTION, the coffee brew prepared in step (ii) is mixed with a whitening agent and a sweetener to produce the coffee beverage. Any known whitening agents and sweeteners may be used in this step. In an exemplary embodiment, the whitening agent may be a liquid such as milk in the amount of 7-15% (e.g. 11.1%) by volume of the coffee brew. For example, 1 US fluid ounce of milk may be mixed into 9 US fluid ounces of coffee brew to make a cup of coffee for consumption.

The sweetener may be a solid such as white granulated sugar in the amount of 1.9-2.2% (e.g. 2.07%) by weight of the coffee brew. For example, 5.5 grams of white granulated sugar may be mixed into 266.2 grams of coffee brew to make a cup of coffee for consumption. In various embodiments, one or more high intensity sweeteners and optional sweetness flavor enhancers may be used to completely or partially replace an amount of the regular white sugar, as along as the sweetness remains unchanged.

Examples of whitening agent include liquid dairy components, such as liquid milk, liquid skim milk, liquid non-fat milk, liquid low fat milk, liquid whole milk, liquid half & half, liquid light cream, liquid light whipping cream, liquid heavy cream, liquid lactose free milk, liquid reduced lactose milk, liquid sodium free milk, liquid reduced sodium milk, liquid dairy fortified with nutrients, such as vitamins A, D, E, K, or calcium, liquid high protein dairy, liquid whey protein concentrate, liquid whey protein isolate, liquid casein concentrate, liquid casein isolate, etc. Examples of whitening agent may include dry dairy components, such as whole dry milk, non-fat dry milk, low fat milk powder, whole milk powder, dry whey solids, de-mineralized whey powders, individual whey protein, casein dairy powders, individual casein powders, anhydrous milkfat, dried cream, lactose free dairy powder, dry lactose derivatives, reduced sodium dairy powder, etc. The present embodiments also include calorie-free dairy, cholesterol free dairy, low calorie dairy, low cholesterol dairy, light dairy, etc. Also included are combinations of any of the above liquid or dry dairy components in any ratio.

Other suitable sweeteners that can be used in the invention are those well known in the art, including both natural and artificial sweeteners. These suitable sweeteners include, e.g. water-soluble sweetening agents such as monosaccharides, disaccharides and polysaccharides such as xylose, ribose, glucose (dextrose), mannose, galactose, fructose (levulose), sucrose (sugar), maltose, invert sugar (a mixture of fructose and glucose derived from sucrose), partially hydrolyzed starch, corn syrup solids, dihydrochalcones, monellin, steviosides, and glycyrrhizin; water-soluble artificial sweeteners such as the soluble saccharin salts, i.e., sodium or calcium saccharin salts, cyclamate salts, the sodium, ammonium or calcium salt of 3,4-dihydro-6-methyl-1,2,3-oxathiazine-4-one-2,2-dioxide, the potassium salt of 3,4-dihydro-6-methyl-1,2,3-oxathiazine-4-one-2,2-dioxide (acesulfame-K), the free acid form of saccharin, and the like; dipeptide based sweeteners, such as L-aspartic acid derived sweeteners, such as L-aspartyl-L-phenylalanine methyl ester (aspartame) and materials described in U.S. Pat. No. 3,492,131, L-alpha-aspartyl-N-(2,2,4,4-tetramethyl-3-thietanyl)-D-alaninamide hydrate, methyl esters of L-aspartyl-L-phenylglycerin and L-aspartyl-L-2,5,dihydrophenyl-glycine, L-aspartyl-2,5-dihydro-L-phenylalanine, L-aspartyl-L-(1-cyclohexyen)-alanine, and the like; water-soluble sweeteners derived from naturally occurring water-soluble sweeteners, such as a chlorinated derivative of ordinary sugar (sucrose), known, for example, under the product description of sucralose; and protein based sweeteners such as thaumatoccous danielli (Thaumatin I and II).

High intensity sweeteners, including sucralose, aspartame, acesulfame potassium, saccharin, neotame, and the like, and combinations thereof, may optionally be employed. High intensity sweeteners (and other sweeteners) may be expressed as an amount to yield the same sweetness as an amount of (referred to herein as “AYSSA”) another sweetener such as sucrose. For these calculations, sucralose is considered to be 600 times as sweet as an equal weight of sucrose, maltitol is considered to be 0.9 times as sweet as an equal weight of sucrose, sorbitol is considered to be 0.6 times as sweet as an equal weight of sucrose, and isomalt is considered to be 0.40 times as sweet as an equal weight of sucrose. Thus, for example, 1 g of sucralose is an AYSSA 600 g of sucrose.

Any suitable colorant or a mixture of different colorants may be used in the present invention, as long as it renders the desired color in the coffee beverage or brew. There are different ways to scientifically characterize the color of a product. For example, a Lab color space is a color-opponent space with dimension L for lightness and a and b for the color-opponent dimensions, based on nonlinearly compressed CIE XYZ color space coordinates. As known to a skilled artisan, the dimensions of the Hunter 1948 Lab color space are represented as L, a, and b, while those of CIE 1976 Lab color space are represented as L*, a*, b* (hereinafter CIELAB). The difference between Hunter and CIE color coordinates is that the CIE coordinates are based on a cube root transformation of the color data, while the Hunter coordinates are based on a square root transformation.

In various embodiments, the coffee beverage produced from the first coffee composition has a CIELAB coordinate of (L1*, a1*, b1*). In contrast, the coffee beverage produced from the second coffee composition has a CIELAB coordinate of (L2*, a2*, b2*). The kind and amount (i.e. C parts) of the colorant is such that 0<ΔL*≤7.89, −16.74≤Δa*<0, and 0<Δb*≤5.08, wherein ΔL*=L2*−L1*, Δa*=a2*−a1*, and Δb*=b2*−b1*. For example, the coffee beverage produced from the first coffee composition may have a CIELAB coordinate of (L1*, a1*, b1*)=(44.01, 28.56, 31.01), and the coffee beverage produced from the second coffee composition has a CIELAB coordinate of (L2*, a2*, b2*)=(51.90, 11.82, 36.09). In some embodiments, the amount of the colorant in term of “C parts” is in the range of from about 1.0 part to about 3.0 parts, such as 1.8 parts, based on 100 parts by weight of the roasted and ground coffee in the first coffee composition. In preferred embodiments, the colorant comprises FD&C Red 40.

In yet other various embodiments, the coffee brew produced from the coffee composition has a CIELAB coordinate of (L1*, a1*, b1*). In contrast, the control coffee brew produced from the control coffee composition has a CIELAB coordinate of (L2*, a2*, b2*). The kind and amount (i.e. C parts) of the colorant is such that 0<ΔL*≤3.78, −3.37≤Δa*<0, and −0<Δb*≤4.73, wherein ΔL*=L2*−L1*, Δa*=a2*−a1*, and Δb*=b2*−b1*. For example, the coffee brew produced from the coffee composition may have a CIELAB coordinate of (L1*, a1*, b1*)=(5.08, 8.41, 5.17), and the control coffee brew produced from the control coffee composition has a CIELAB coordinate of (L2*, a2*, b2*)=(8.86, 5.04, 9.90). In some embodiments, the amount of the colorant in term of “C parts” is in the range of from about 1.0 part to about 3.0 parts, such as 1.8 parts, based on 100 parts by weight of the roasted and ground coffee in the first coffee composition. In preferred embodiments, the colorant comprises FD&C Red 40.

As described above, any suitable flavorant or mixture of flavorants may be used in the present invention. In various embodiments, the amount of the flavorant present in the first coffee composition in term of “(F−ΔF) parts” may be simply calculated based on the values of F and ΔF, relative to 100 parts by weight of the roasted and ground coffee in the first coffee composition. For example, F=2.0-4.0 such as 3.08, and (F×20.1%)≥ΔF≥(F×13.0%). In preferred embodiments, the flavorant comprises strawberry shortcake flavorant.

Strawberry shortcake flavorant is defined as a flavorant that imparts a strawberry shortcake taste in the coffee beverage or brew. While it is difficult to give a scientific definition of strawberry shortcake taste, it is more convenient to define the taste by referring to a representative recipe for making a traditional strawberry shortcake, the taste of which will be clearly identifiable to a skilled food technologist. For example, a representative recipe that can be used to prepare a typical strawberry shortcake which consists of an 8-inch round cake and two layers of strawberries topped with whipped cream will include the following ingredients: 3 pints fresh strawberries, 0.5 cup white sugar, 2.25 cups all-purpose flour, 4 teaspoons baking powder, 2 tablespoons white sugar, ¼ teaspoon salt, ⅓ cup shortening, 1 egg (beaten), ⅔ cup milk; and 2 cups whipped heavy cream. To make the strawberry shortcake these ingredients are then combined in the following manner. First, slice the strawberries and toss them with ½ cup of white sugar, and set aside. Second, preheat an oven to 425° F. (220° C.) and grease and flour one 8 inch round cake pan. Third, in a medium bowl combine the flour, the baking powder, the 2 tablespoons of white sugar and the salt to form a mixture. Fourth, use a pastry blender to cut the shortening into the mixture until it resembles coarse crumbs. Make a well in the center of the mixture and add the beaten egg plus milk, then stir until just combined to form a batter. Fifth, spread the batter into the greased and floured pan and bake at 425° F. (220° C.) for 15 to 20 minutes or until golden brown. Let the cake cool partially in the pan on the wire rack. Sixth, slice the partially cooled cake in half, making two layers, and then place half of the strawberries on one layer of cake and top with the other layer of cake. Seventh, cover the stacked cakes with the remaining strawberries and top with the whipped cream.

The following examples are provided for illustrative purposes only, and are in no way intended to limit the scope of the present embodiments.

EXAMPLES

In the following examples, a Mr. Coffee ADC brewer was used to brew roasted and ground coffees. The materials used include (1) Dunkin Donuts Original Blend Coffee Lot#4,016,230,101,038, commercially available from The J.M.
